SPRING-BED-BOTTOM FABRIC.

To all whom it may 00 ncernf Be itknown that I, EUGENE GREGORY, of lilichigan City, in the county of Laporte and State of Indiana, have invented certain new and useful Improvements in Spring- Bed-Bottom Fabrics; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in spring bed bottoms, and resides in the novel construction thereof hereinafter described.

The object of the invention is to provide a novel form of spring mattress or bottom for beds; which will afford ample support for every portion of the bedding placed thereon, and will yield at the portions where the most pressure is exerted thereon, so as to comfortably adjust itself to the body of the wearer; and will maintain its shape and flexibility under very hard and long usage with scarcely any appreciable wear; and which moreover can be attached to a bed or frame without being put under such tension, as ordinary spring bed bottoms require.

The bed bottom in brief consists of a metal fabric made up of single wire figure eight springs ending in short hooks, these springs hooking laterally and longitudinally into rings of wire to form the complete body of the fabric; and this fabric bottom is attached to the frame or rails, by any convenient means, preferably by wire loops passing through the rails.

I will now explain the invention in detail with reference to the accompanying drawings which show a spring bed bot-tom embodying the invention.

In said drawingsFigure 1 is a top plan view partly broken of a complete bed bottom, the upholstered mattress being partly broken away. Fig. 2 is an enlarged detail view of several of the spring members of the bed-bottom and their connections. Fig. 3 is an edge view of Fig. 2. Fig. 4 is an enlarged detail view of the bed bottom springs and its wire loops by which the springs are con nected to the frame.

In Fig. 1 of the drawings I have shown my novel bed bottom or fabric as applied to a folding bed. This is fully described in my application for folding bed or couch filed April 13, 1911, Serial No. 620,903, of which Specification of Letters Patent.

Original application filed April 13, 1911, Serial No. 620,903.

Patented Dec. 5, 1911..

Divided and this application filed June 12,

Serial No. 632,721. a

the present application is a division; it is therefore unnecessary herein to describe the folding frame in detail, and the invention is not restricted to any particular construction of frame, bed or couch to which the bed bot-tom is attached.

As shown in the drawings the bed bottom fabric is composed of members a- (preferably wire rings). arranged in following order; to every ring is connected four peculiar wire springs 5; each spring (except those at the outermost sides of the fabric) is interposed between and connects two adjacent rings 4:. Each spring 5 is preferably made of a single stiff steel wire which is bent intermediate its ends into an approximately figure 8 shape, forming two flat loops 5 lying in substantially the same plane, while the two ends of the wire 5" are extended in opposite directions from between the loops but in substantially the same plane; and the extremities of these ends or arms 5 of the spring are hooked as at 5, to engage the rings. The spring members are so proportioned that the flat loops of the spring members and the rings, or devices equivalent to the rings are so close together that a silver dollar could hardly find space to drop facewise through the bed bottom at any point; and in such bottom practically every part of any superposed body, such as an upholstered mattress M placed on such a bed bottom, will be directly supported.

The outermost spring members 5 at the sides and ends of the wire bottom are connected to the adjacent side bars 1. 1" and end bar 1* of a supporting frame which may be of any suitable construction. As shown wire loops 6 are attached to the side bars 1, 1 1 and the outer arms of the outside spring-members 5 are directly engaged with these wire loops 6; while the outer arms of the outermost end spring-members 5 may be connected to the loops on the ends of the frame by means of wire links 6, as I have found it is unnecessary in practice to extend the spring fabric the entire length of the frame, it being sufficient if it extends under such portions of the mattress as will be subjected to the weight of a person lying thereupon.

In order to enable the bed bottom to be folded straight across the center of the spring-bottom if desired, I may substitute for the central transverse row of springmembers 5, helical springs 7 which extend across the bed bottom. The outermost springs 7 may be connected with plates 7 attached to the bars 1, 1 of the same section of the top frame as described in my aforesaid application; these plates 7 a can be screwed or bolted to the said bars in any suitable manner. lVith this construction when the frame is extended the spring mattress lies fiat and smooth and taut, without any excessive contracting pressure upon the members of the frame, such as would tend to distort the latter or such as would be necessary with a woven wire mattress.

By reason of.the peculiar form of the springs the bed-bottom is very thin and yet covers the surface almost as closely as a woven wire mattress. By reason of the peculiar curvature of the springs the bedbottom or fabric will readily depress in curves, not in angles, at the place where the most pressure is applied thereon,as at the shoulders or hips of a person lying there upon,without unduly distorting any other portion of the mattress; and it will not sag and become hammocked like ordinary springs.

What I claim is:

1. A spring fabric or bottom for beds, comprising a series of spring-members each bent into opposite coils approximately resembling a figure 8, the ends of the wire extending in opposite directions from between the coils of such figure and lying in substantially the same plane as the coils, and intermediate members engaged by the said spring-members.

2. A spring bottom for beds, comprising a series of members or rings arranged in parallel rows, and a series of springme1nbers each formed of a stout wire bent into opposite fiat coils lying in substantially the same plane and approximately resembling a figure 8, with the ends of the wire extended in opposite directions from between the coils to form arms in substantially the same plane as the coils, said arms being engaged with the rings to form a fabric.

In testimony that I claim the foregoing as my own, I affix my signature in presence of two witnesses.
